Bob and Nancy are two American tourists, who love travelling and doing jigsaw puzzles! Bob is a well-off, retired computer programmer. He likes doing jigsaw puzzles more than travelling, but his wife Nancy always succeeds in persuading him to pack his suitcase and visit yet another city of the world. Thats why you can find both of them on all the puzzles of the Cities of the World series. They travel together with the artist Fleroux, but that doesnt always work out so well for them. Because in every city they travel to, they are confronted with unexpected situations. And what exactly do they experience on their trips? In order to find that out, you first have to put the jigsaw puzzle together correctly. Only then can you actually see that the situation shown on the packaging has a funny outcome in the puzzle.
